摘要

的目的。根据国内环境立法的新要求,介绍了国家对能源企业对环境的负面影响进行监管的技术原则。环境保护活动的既定原则规定了在引进现有最佳技术的基础上对排放进行技术监管,并区分国家监管措施,以确保火电设施的环境安全。在现行环境立法的框架内,有必要确定具有致癌特性的高毒性物质的排放标准。讨论了1mw以下低功率锅炉烟气中致癌性多环芳烃的主要代表。研究方法包括对实验数据进行归纳,并采用统计数据处理方法对锅炉烟气中苯(a)芘等致癌物的含量进行计算评估。确定了在火电厂小功率锅炉运行过程中,在工业环境控制系统中考虑致癌性多环芳烃危害贡献的必要性。研究结果可用于能源企业执行新环境立法在致癌排放技术监管方面的要求,包括制定改善环境绩效指标的措施。

Toxicity of carcinogenic pahs in boiler flue gases thermal capacity up to 1 Mw
THE PURPOSE. In accordance with the new requirements of domestic environmental legislation, technological principles of state regulation of the negative impact of energy enterprises on the environment have been introduced. The established principles of environmental protection activities provide for technological regulation of emissions based on the introduction of the best available technologies, as well as differentiation of state regulatory measures to ensure the environmental safety of thermal power facilities. Within the framework of the current environmental legislation, it is shown that it is necessary to determine emission standards for highly toxic substances that have carcinogenic properties. The main representatives of carcinogenic PAHs found in the flue gases of boilers of low power up to 1 MW are considered.METHODS. The research methods included the generalization of experimental data and thecalculated assessment of the content of carcinogenic emissions, including benz(a)pyrene in the flue gases of boilers using statistical data processing methods.RESULTS. The necessity of taking into account the contribution of the harmfulness of carcinogenic PAHs in the system of industrial environmental control at thermal power facilities during the operation of low-power boilers is determined.CONCLUSION. The results of the study can be used at energy enterprises to implement the requirements of the new environmental legislation in terms of technological regulation of carcinogenic emissions, including for the development of measures to improve environmental performance indicators.
